I had found the immigration and had been working on the assumption that Elizabeth was the daughter of Robert and Elizabeth from Redruth. (You may have this)
Marriage is normally in the Brides parish so James may have been from anywhere. Unfortunately the marriage Cert wont tell us where he was from (only where he was living at the time of marriage,which according to the newspaper announcement was Redruth) Hopefully the fathers name will help.
